@Baldrick Looking at the pictures, two thoughts came to my mind. Sorry, if you find it offensive! Please don’t me wrong. 😊
1: It wasn’t roasted properly / evenly, assuming the bag was from a single roast! I do not think this is correct.
2: They produced three roasts - medium dark and two variations of darker. They mixed them together!
I don’t know what @DavecUK thought of it from the picture.
